Prototype design pattern
The last pattern we will see in this chapter is the Prototype pattern. Like all creational patterns, this too comes in handy when creating objects, and it is very common to see the Prototype pattern surrounded by more patterns.
While with the Builder pattern, we are dealing with repetitive building algorithms and with the factories we are simplifying the creation of many types of objects; with the Prototype pattern, we will use an already created instance of some type to clone it and complete it with the particular needs of each context. Let's see it in detail.
The aim of the Prototype pattern is to have an object or a set of objects that is already created at compilation time, but which you can clone as many ...
